IQRX.
Coherent Optical Receiver
The IQRX is a “gold standard” coherent receiver for the measurement of coherent modulation formats such as QPSK, 64QAM and OFDM.
Its high-bandwidth, low-noise architecture makes it ideal for high-quality, low-distortion coherent signal measurement.
The new IQRX-1005 model is the world’s first commercially-available coherent receiver to enable coherent signal testing in the O-Band, with models available in the C/L-Band.
High-performance, low noise coherent receiver
IQRX is designed and built using the highest-performing discrete fiber optic components to provide superior fidelity measurement of coherently modulated signals. To minimize noise, IQRX does not use a transimpedance amplifier (TIA), a component often found in commercially available ICRs.
Four single-ended outputs
Designed to be used with any real time oscilloscopes with sufficient bandwidth and sampling rate, the single-ended outputs make it convenient to pair with the four input channels of most oscilloscopes. In high-bandwidth oscilloscope configurations where there are only two channels per unit, IQRX’s slim profile and wide footprint enable it to be placed between multiple oscilloscope units.
Dual polarization measurement
IQRX houses polarization selective hardware to characterize polarization multiplexed signals. LO input, signal output and internal laser outputs all use polarization maintaining (PM) fiber for the highest versatility.
Built-in narrow linewidth tunable laser*
IQRX comes with a built-in narrow 25 KHz instantaneous linewidth laser, making it perfect for coherent modulation formats that require high phase stability.
19 inch rack mountable
IQRX can be supplied with optional mounting brackets for easy mounting in 19 inch racks.
